What is Aerosol impaction?
- Aerosol impaction Aerosol Impaction is the process in which particles are removed from an air stream by forcing the gases to make a sharp bend.
- Why is this done?
- Particles above a certain size possess so much momentum that they can not follow the air stream and strike a collection surface which is available for later analysis of mass and composition.
- What else is interesting about this?
- Removal of particles from an air-stream by impaction followed by mass and composition analysis has always been a different approach as to filter sampling, yet has been little utilized for routine analysis because of lack of suitable analytical methods.
- What are some of the advantages?
- The most clear and important advantage of impaction, as opposed to filtration, is that two key aerosol parameters, size and composition, can be simultaneously established.
- Are there any other advantages?
- There are many advantages of impaction as a sampling method.
- What else is interesting?
- 

For two of the most common configurations, an orifice and an infinite slot, theoretical predictions can be made and empirically verified that give the cuts point and shape of the collection efficiency of an impaction stage.
